(2) Leak detection for pressure abnormalities When there is a leak in the heat network, it is necessary to make up water when there is water leaking into the heat network from the outside, it is necessary to release water to maintain the dynamic balance of water in the heat network. Heat network is a closed loop system with pressure, in the normal operation of the process, the water volume in the heat network to maintain a constant.
There are many factors affecting the leakage of heat pipes, which can be broadly categorized as the following: bad quality of pipes and fittings poor welding quality of joints the impact of construction of other projects high water pressure and water hammer damage poor corrosion and insulation performance of pipelines large traffic load caused by soil settlement shallow pipeline burial layer and experience continuous low temperatures in winter heating media led to corrosion inside the pipeline not timely Inspection and repair as well as the use of pipelines over the age. Therefore, to solve the pipeline leakage must be prevented in advance, do a good job in advance of the pipeline leak detection work so the following I will take you to understand how the thermal pipeline waterproof leak repair.ġ, thermal pipeline leakage causes and effects Prefabricated direct buried hot water insulation pipe heat pipe leakage will cause energy waste, affect the heat users' heating, bring extra maintenance burden to the heating enterprise.
